ROTO GRIP SHATTER I FIRST TOOK THIS BALL TO THE LANE THAT I HAD TESTED THE BERSERK ON. IT HAD JUST A FEW GAMES ON THE LANE AND STILL THE 39' HOUSE SHOT. THIS BALL WAS AS STRAIGHT AND CLEAN THROUGH THE FRONTS WITH A GREAT BIG ANGULAR MOVE ON THE BACKEND, WITH ABSOLUTELY  NO DEFLECTION. FOR MY GAME, ANGULAR IS USUALLY PART OF MY DESCRIPTION. I THEN TOOK IT TO A FRESHLY OILED 39'HOUSE SHOT LANE WITH EXTREMELY CLEAN BACKENDS. HAD PRETTY MUCH THE SAME RESULTS...SUPER EASY TO GET IT THROUGH THE FRONTS AND A BACKEND MOVE THAT IS AWESOME. GREAT JOB ROTO GRIP. THIS BALL HAS IT ALL GOING FOR IT:  NICE ROLL, STRONG HOOK, BIG HIT AND GREAT EYE APPEAL.
